The DYMO Rhino 18057 Heat-Shrink Tube is designed for professional wire and cable identification in electrical, networking and industrial environments. It allows users to print clear, permanent identification directly onto heat-shrink tubing using compatible DYMO Rhino industrial label makers. The 19mm width provides a larger labelling area, while the 3:1 shrink ratio enables the tube to fit securely around compatible cables after heating. Its durable construction helps maintain readable identification in demanding working conditions.
